The chronotype refers to the differences in performance that each individual has in relation to the periods of sleep and wakefulness throughout the 24 hours of the day.
People organize their lives and activities according to a 24-hour cycle, that is, with certain times of waking, entering work or school, performing leisure activities and bedtime, being able to have more or less income in certain hours of the day, which influence and are influenced by the biological cycle of each.
There are periods of the day when the person's income is higher or lower, which has to do with their chronotype. Thus, people are classified according to their biological rhythms in morning, intermediate and evening, according to the periods of sleep / wake, also known as circadian cycle, that present in the 24 hours of the day.
Types of biological clock
According to your biological clock people can be classified as being:
1. Morning or daytime
The mornings are individuals who prefer to wake up early and who perform well in activities that start in the morning, and often find it difficult to stay up late. These people feel sleepy earlier and have difficulty staying properly focused at night. For these people to work in shifts can be a nightmare because they are very stimulated by the clarity of the day.
These people represent about 10% of the world's population.
2. Evening or night time
Evenings are those people who are more productive at night or early in the morning and who prefer to stay up late and go to sleep at dawn, having a higher performance in their activities at that time.
Their sleep / wake cycle is more irregular and has more difficulty concentrating during the morning, and they present greater problems of attention and suffer more of emotional problems, needing to consume more caffeine throughout the day, to stay awake.
Evenings represent about 10% of the world's population.
3. Intermediate
Intermediaries or indifferents are those who adapt to schedules more easily in relation to the morning and evening, and there is no preference for a specific time to study or work.
Most of the population is intermediate, which means that most people can adjust to the times imposed by society, more easily than the evening and morning.
How Biological Clock Works
The biological clock is maintained by the rhythm of the person himself and by the imposition of society, with hours to work from 8am to 6pm for example, and to sleep from 11pm.
What happens when you enter summer time may be indifferent to people with an intermediate chronotype, but it can cause some discomfort in the morning or evening. Normally after 4 days it is possible to be completely adapted to daylight saving time, but for morning or afternoon guests may experience more sleep, less willingness to work and exercise in the morning, lack of food hunger and even discomfort .
